The number of neutrons in the nucleus of an atom which has 26 electrons and has a mass number 56 are :
- A. 26
- B. 36
- C. \) 30
- D. 56
Step-by-step solution
For a neutral atom, number of electrons equals number of protons. Given 26 electrons, protons = 26. Mass number = protons + neutrons = 56, so neutrons = 56 - 26 = 30.
